This mixture may be applied witli a swab or brush, or with the spray 

 pump, if used warm. Oue thorough application in the fall, aud another before 

 growth commences in the spring, should be made when used against woolly 

 aphides. This is also an excellent wash to remove moss and lichen from trees 

 and bushes, aud if used for this purpose alone, half the amount of soap is 

 sutlicient. 



FUNGICIDES. * 



No. 4. — Bordcaii.r Mhrtnre. — The formula recommended by the Board of 

 Horticulture for summer use is as follows : — 



Sulphate of copper (bUiestone) 4 lt)s. 



Fresh unslaked lime 4 .. 



Water ( soft ) 40 gallons. 



Double strength for winter use: — 



Sulphate of copper (bluestone) S to 10 lbs. 



Fresh unslaked lime S Tbs. 



Water (soft) 40 gallons. 



Bulletin 60 of the Washington Experiment Station recommends for apple 

 tree anthraenose even of greater strength, viz. : — 



Copper sulphate (bluestone) 12 lbs. 



Quick-lime S „ 



Water 50 gallons = 40 Imp. gal. 



The ordinary double strength mixture, viz., S, S, 40. is, however, sufficient 

 for general purposes. 



For poisoned Bordeaux mixture add 4 ozs. Paris green to the above. 

 Make the Paris green into a paste by adding a little warm water and then 

 Iiour into the barrel and stir thoroughly. The quantities are easily remem- 

 bered, being all fours, viz. : — 



Sulphate copper 4 lbs. 



Lime 4 „ 



AVater 40 gallons. 



Paris greeu 4 ounces. 



The greatest care sliould be used in preparation of this mixture. 

 If but a small quantity is to be used, prepare as follows : — Weigh out 

 four pounds of fresh (never air-slaked) lime, add to it, gradually, warm 

 water, a little at first, more as the slaking proceeds, being sure that at 

 no time the lime lacks water enough, stirring all the while with a hoe. Con- 

 tinue adding water till a soft milk of lime is the. result. Dissolve in a bucket 

 or half barrel (never a metal vessel) four pounds of bluestone, using warm 

 water to hasten solution. When this is completely dissolved, dilute both lime 

 and bluestone with about 10 gallons of water. Strain the milk of lime into 

 the .spray tank through a rather close-meshed wire gauze, thus preventing any 

 lumps, rocks, or fibers from going into the tank. Then, while one stirs the 

 material in the tank with a hoe, another man gently adds the bluestone water, 

 seeing that no lint or trash goes in by this means either. Then fill the tank
